Phase 1: Boot Sequence & Architecture

ARM Boot sequence & Bootloaders (U-Boot)

Understand how processors load and transition to the Linux Kernel. Master ROM Bootloader, SPL, and U-Boot.

Phase 2: Custom OS Creation (Yocto & Buildroot)

Yocto Project & Buildroot Integration

Learn how to generate customized lightweight Linux distributions using meta-layers, recipes, and tasks.

Phase 3: Hardware Interfacing & Device Trees

Device Tree Syntax & Pin Control

Describe hardware configurations to the kernel using device tree source files (DTS) and pin multiplexing.

Phase 4: Kernel Module & Driver Development

Linux Character Device Drivers

Write custom C kernel modules that execute inside kernel space, register major/minor numbers, and manage file operations.

Phase 5: Secure Production & Sysfs

Sysfs, User Space & Secure Boot

Build secure, optimized user environments using custom build scripts and read-only filesystems.
